Raclage des données Web expliquées par Semalt

by
Jan 29, 2018

Web scraping est le processus de collecte de données utiles ou relationnelles à partir de pages Web spécifiées et de conversion dans un format spécifié. Les données éraflées sont généralement exportées dans une base de données ou une feuille de calcul. Les avantages et l'importance du processus ne peuvent pas être surestimés. C'est pourquoi il est devenu une pratique courante parmi les organisations.

Le seul problème avec le processus est qu'il ne peut pas être fait manuellement. Pour que toute organisation puisse tirer un bénéfice tangible du processus, les données doivent être supprimées périodiquement de centaines de pages Web. C'est là qu'interviennent  les outils de grattage. Les outils sont utilisés pour gratter les données de nombreuses pages avec autant de rapidité et de précision.

Présentation de la barre d'outils de données, un outil de récupération de données efficace

Il existe plusieurs outils de récupération de données mais Data Toolbar se distingue par son efficacité et sa simplicité. Beaucoup de gens ont besoin d'un raclage de données, mais très peu de personnes ont des compétences en programmation. Ainsi, tous les outils d'extraction de données qui ne nécessitent pas de connaissances en programmation sont généralement très demandés. La barre d'outils de données ne nécessite pas de compétence de programmation, c'est donc un excellent choix.

Cet outil est très intuitif et explicite. Il est conçu pour automatiser le processus de grattage Web pour tous les navigateurs..Il est si simple que vous avez seulement besoin de pointer vers les champs de données requis et l'outil les extraira pour vous en quelques minutes. Il est capable d'extraire des milliers de données de différents types de sites Web en quelques minutes. Comme mentionné précédemment, il ne nécessite aucune compétence technique.

Comment utiliser l'outil

Il suffit de cliquer sur tout le champ de données et les images qui doivent être grattées les unes après les autres. Pour sélectionner plusieurs images et champs de données, accédez à la page "Détails" pour ajouter des champs l'un après l'autre. Après cela, vous devriez également vérifier "NEXT" page option. C'est tout. L'outil parcourra l'ensemble du site Web page après page pour récupérer le contenu requis. Après l'extraction, l'outil enregistre les données dans un script SQL, un fichier HTML ou une feuille de calcul Excel en fonction de votre choix.

Versions du logiciel

Il existe deux versions de l'outil: la version gratuite et la version payante. Heureusement, la version gratuite de l'outil a les mêmes fonctions avec la version premium. Ils n'expirent pas tous les deux, ils n'ont pas besoin d'inscription et n'autorisent pas les publicités.

Vous devez vous demander pourquoi les gens devraient payer pour la version premium s'il n'y a pas de différence entre les deux versions. Il y a une grande différence. La sortie de la version gratuite est limitée à 100 lignes alors que celle de la version premium n'a pas de limite.

Donc, vous pouvez utiliser la version gratuite pour la version d'essai et lorsque vous êtes satisfait de l'outil, vous pouvez passer à la version premium avec seulement 24 $.

Versions du navigateur

En termes de navigateur pris en charge, la barre d'outils de données existe en deux versions. Une version prend en charge Edge et Internet Explorer (les deux pour Windows) tandis que l'autre version est à la fois pour Firefox et Chrome. En termes de qualité, les deux versions produisent la même qualité de sortie.

Pourquoi ne pas essayer la version gratuite de l'outil de grattage des données puisqu'il est gratuit et que vous n'avez rien à perdre? Vous pouvez ensuite passer à la version premium si vous l'aimez. Et si vous n'êtes pas satisfait, vous pouvez simplement rechercher un autre outil d'extraction de données.

Can web scraping be done on mobile apps or websites, Max?
Max Bell
Web scraping primarily focuses on extracting data from websites rather than mobile apps, Liam. However, if a mobile app's content is served through a website (e.g., an API endpoint or HTML views), scraping techniques can be adapted to extract data from these sources. If the mobile app itself does not provide accessible data, scraping may not be applicable. It's important to evaluate the specific scenario and ensure compliance with relevant guidelines and terms of service when scraping mobile apps or websites.
Oliver Powell
